発明の背景
生体検査は、癌腫瘍、悪性前状態、その他の病気や疾患をもつ患者を診断するのに使用される重要な手順である。典型的には、癌の場合、医師が触診や***X線撮影、X線、または超音波撮像のような手順によって疑わしい状況が存在することを確証するとき、生体検査が行われる。この生体検査は細胞が癌であるか否か、癌のタイプ、癌を治療するのにどのような治療を使用すべきかの決定を助ける。生体検査は切開手術または経皮手術によって行われてもよい。切開生体検査は、外科用メスを使用し目標領域を直接目視する侵襲性外科手順であるが、塊の全てを除去し(摘出生体検査)、または塊の一部を除去する(切開生体検査)する。これに対し、経皮生体検査は通常、比較的小さな切開を通してニードル状の器具を使用して行われ、盲目的にまたは撮像装置の援助により通常行われ、針吸引細胞診(FNA)またはコア生体検査のいずれでもよい。FNA生体検査では、個々の細胞または該細胞の集団を得て細胞学的検査し、パパニコロー塗抹標本におけるように準備してもよい。コア生体検査では、用語が示唆するように、組織のコアまたは破片を得て組織学的検査を行なう。組織学的検査は凍結部またはパラフィン部を介して行ってもよい。生体検査が行われる1つの重要な領域は、胸部腫瘍の診断である。
BACKGROUND OF THE INVENTION Biopsy is an important procedure used to diagnose patients with cancerous tumors, premalignant conditions, and other diseases and disorders. Typically, in the case of cancer, a biopsy is performed when the physician confirms that a suspicious situation exists by procedures such as palpation, mammography, x-ray, or ultrasound imaging. Whether the biopsy is a cell cancer, help determine whether to use what therapy to treat type of cancer, the cancer. A biopsy may be performed by open surgery or percutaneous surgery. An incisional biopsy is an invasive surgical procedure that uses a scalpel to directly view the target area, but removes all of the mass (excised biopsy) or removes a portion of the mass (incision biopsy) Do. In contrast, percutaneous biopsy is usually performed using a needle-like instrument through a relatively small incision, usually performed blindly or with the aid of an imaging device, and needle aspiration cytology (FNA) or core organisms. It may be any of examinations. For FNA biopsy, individual cells or populations of the cells may be obtained, cytologically examined, and prepared as in a Pap smear. In core biopsy, as the term suggests, a core or fragment of tissue is obtained and a histologic examination is performed. Histological examination may be performed via the frozen part or the paraffin part. One important area where biopsies are performed is the diagnosis of breast tumors.
バイオプシーによって提案された真空支援生体検査システムは、胸部障害部をカニューレに吸引し、該障害部の捕獲した縁を切断して生体検査サンプルを得ることを必要とする。この装置は真空を使用して組織を開口した管状装置の側に収集し、回転コア採取器を使用して採取した組織を切断する。回転コア採取器は管状部内でスライド可能であり、引き戻して回転コア採取器内に採取した組織を除去することができる。回転コア採取器内で追加の探り針を使用して組織を回転コア採取器の外に押し出すことができる。この装置は、該装置の中心部の回りに360°その軸上で回転させてサンプルを取り出すことができる。典型的には、医師は6から8個のコアを採取する。この装置の1つの利点は、医師は追加の生体検査サンプル用の装置を取り除く必要がないことである。しかし、腫瘍それ自体は全てのコア採取操作後に再び埋め込まなければならない。これは再配置に実質的な努力し、目標の疑いのある塊が横孔に埋め込まれたことを確認することを必要とする。腫瘍は、非常に強固なので吸引器に屈しないし、カニューレの横孔に入るのに必要なように変形しない。また医者は現在、装置を使用して該装置をその長手軸回りに回転させることによりコアを円形に連続させ、または吸引ヘッドを横移動させてコアを直線に並べている。 The vacuum assisted biopsy system proposed by the biopsy requires aspiration of the chest lesion into a cannula and cutting of the captured rim of the lesion to obtain a biopsy sample. The device uses a vacuum to collect tissue to the side of the open tubular device and a rotating corer is used to cut the collected tissue. The rotating corer is slidable within the tubular section and can be withdrawn to remove tissue collected in the rotating corer. An additional stylet can be used within the rotating corer to push tissue out of the rotating corer. The device can be rotated about its axis 360 ° around the center of the device to remove the sample. Typically, a physician takes 6 to 8 cores. One advantage of this device is that the physician does not have to remove the device for the additional biopsy sample. However, the tumor itself has to be re-implanted after every core harvesting operation. This requires a substantial effort to reposition and ensure that the mass suspected of being a target has been embedded in the lateral hole. The tumor is so rigid that it does not yield to the aspirator and does not deform as needed to enter the lateral hole of the cannula. Also, physicians currently use the device to rotate the device about its longitudinal axis to continue the core circularly, or to move the suction head laterally to align the core.
図9は、腫瘍41を固定するように活性化された付着プローブ1を示す。生体検査手順中に腫瘍をプローブに固定するために、穿通セグメント3の回りの表面領域を冷却する。ガスまたは液体のいずれかをその供給源から穿通セグメントに導く。外科医がガスを使用する場合、該ガスが冷却剤入口チューブ10のオリフィス11を通って導出されるにつれ、ガスはジュール−トムソン効果により穿通セグメント回りの表面領域を凍結させる。ガス源は高圧縮タンクまたはホイペット(whippet)とすることができる。表面領域は約0℃から−60℃の温度範囲に凍結する。この温度範囲では、冷却された表面領域は腫瘍細胞を除去して腫瘍細胞分析を行なうことを妨げない。この温度範囲に表面領域を冷却するのに、比較的小さな量のガスまたは液体が必要である。オリフィスに存在しおよび管状空間16に沿って逆流するガスまたは液体は、プローブから排出される。冷却された表面領域は該冷却表面領域の回りに接触する腫瘍細胞の薄層を凍結させ、腫瘍はプローブに固定される。身体組織の冷却管状容積は図9に符号42で示されている。 FIG. 9 shows the adhesion probe 1 activated to fix the tumor 41. The surface area around the penetrating segment 3 is cooled in order to fix the tumor to the probe during the biopsy procedure. Either gas or liquid is directed from its source to the penetration segment. If the surgeon uses a gas, the gas freezes the surface area around the penetration segment by the Joule-Thompson effect as the gas is drawn through the orifice 11 of the coolant inlet tube 10. The gas source can be a high compression tank or a whippet. Surface area of from about 0 ° C. - frozen temperature range of 60 ° C.. In this temperature range, the cooled surface area does not prevent tumor cells from being removed for tumor cell analysis. A relatively small amount of gas or liquid is required to cool the surface area to this temperature range. Gas or liquid present at the orifice and backflowing along the tubular space 16 is evacuated from the probe. The cooled surface area freezes a thin layer of tumor cells contacting around the cooled surface area, and the tumor is fixed to the probe. The cooled tubular volume of body tissue is shown at 42 in FIG.
図16から図19は装置の使用状態を示す。図16は、腫瘍を覆う皮膚に作られた切口を通して挿入されている付着プローブ1とカニューレ20を示す。患者の胸部78及び皮膚79が概略的に示されている。腫瘍、障害、その他疑いのある塊80が胸部内に位置して、柔らかい組織および脂肪のある組織により囲まれている。超音波スキャナまたは他の撮像装置を使用して、腫瘍および胸部に挿入された装置を含む胸部の像を得る。外科医は撮像装置からのディスプレイを使用してプローブおよびカニューレを腫瘍に誘導するのを支援する。 16 to 19 show the use of the device. FIG. 16 shows the adhesion probe 1 and the cannula 20 being inserted through an incision made in the skin covering the tumor. The patient's chest 78 and skin 79 are shown schematically. A mass 80 suspected of having a tumor, injury or otherwise is located in the chest, surrounded by soft tissue and tissue with fat. Using an ultrasound scanner or other imaging device to obtain an image of the chest, including the inserted device to the tumor and breast. The surgeon uses the display from the imaging device to help guide the probe and cannula to the tumor.
図18は、腫瘍80を固定するために起動されている付着プローブ1を示す。生体検査手順中に腫瘍をプローブに固定するために、穿通セグメント3の回りの表面領域を冷却する。ガスまたは液体のいずれかが供給源から穿通セグメントに導かれる。外科医がガスを使用する場合、該ガスが冷却剤入口チューブ10のオリフィス11を通って導出されるにつれ、ガスはジュール−トムソン効果により穿通セグメント回りの表面領域を凍結させる。冷却された環状体積の身体組織は図18に符号81で示されている。ガス源は高圧縮タンクまたはホイペットとすることができる。表面領域は約0℃から−60℃の温度範囲に凍結する。この温度範囲では、冷却された表面領域は腫瘍細胞を除去して腫瘍細胞分析を行なうことを妨げない。この温度範囲に表面領域を冷却するのに、比較的小さな量のガスまたは液体が必要である。オリフィスに存在しおよび管状空間16に沿って逆流するガスまたは液体は、プローブから排出される。冷却された表面領域は該冷却表面領域の回りに接触する腫瘍細胞の薄層を凍結させ、腫瘍はプローブに固定される。 FIG. 18 shows the attachment probe 1 activated to fix a tumor 80. The surface area around the penetrating segment 3 is cooled in order to fix the tumor to the probe during the biopsy procedure. Either gas or liquid is directed from the source to the penetration segment. If the surgeon uses a gas, the gas freezes the surface area around the penetration segment by the Joule-Thompson effect as the gas is drawn through the orifice 11 of the coolant inlet tube 10. The cooled annular volume of body tissue is shown at 81 in FIG. The gas source can be a high compression tank or a whippet. Surface area of from about 0 ° C. - frozen temperature range of 60 ° C.. In this temperature range, the cooled surface area does not prevent tumor cells from being removed for tumor cell analysis. A relatively small amount of gas or liquid is required to cool the surface area to this temperature range. Gas or liquid present at the orifice and backflowing along the tubular space 16 is evacuated from the probe. The cooled surface area freezes a thin layer of tumor cells contacting around the cooled surface area, and the tumor is fixed to the probe.
カニューレ回転機構は、リードねじ111(アクチュエータロッドとしても機能する)とリードねじナット113からなっている。リードねじナットは、先端閉鎖ヘッド内で、ピストンシリンダ106の先端に配置されている(先端閉鎖ヘッドと一体に形成されていてもよい)。リードねじは、外側にねじを備えたチューブと、該チューブを貫通するルーメンとからなっている。リードねじの基端はピストン109に長手方向に固定され、これによりリードねじのルーメンはピストンの穴と連通している。(カニューレはリードねじのルーメンを貫通している。)リードねじナットはリードねじを受け入れるように適合されている。リードねじはリードねじナットにねじ込まれ、これによりリードねじは、ピストンシリンダ106内から、リードねじナットを貫通し、シリンダの外部に延びている。カニューレ20は、リードねじのルーメンを貫通し、リードねじに直接または間接的に回転可能に固定されている。ピストンが平行移動すると、リードねじはピストンの操作で平行移動し、該平行移動を介して回転し、リードねじナットを貫通する。リードねじは、1回転当たり(1)インチのピッチを有し、これにより1インチの平行移動毎に、リードねじは1回転する。カニューレがカニューレに回転可能に固定されているため、リードねじの回転はカニューレに伝達される。 The cannula rotation mechanism comprises a lead screw 111 (also functioning as an actuator rod) and a lead screw nut 113. The lead screw nut is disposed at the tip of the piston cylinder 106 (which may be integrally formed with the tip closure head) in the tip closure head. The lead screw consists of a tube with an outer thread and a lumen through the tube. The proximal end of the lead screw is longitudinally fixed to the piston 109 so that the lumen of the lead screw is in communication with the bore of the piston. (The cannula passes through the lumen of the lead screw.) The lead screw nut is adapted to receive a lead screw. The lead screw is screwed into the lead screw nut so that the lead screw extends from within the piston cylinder 106 through the lead screw nut and out of the cylinder. The cannula 20 penetrates the lumen of the lead screw and is rotatably fixed directly or indirectly to the lead screw. When the piston translates, the lead screw translates in operation of the piston, rotates through the translation, and penetrates the lead screw nut. Lead screw have a pitch per revolution (1) inch, thereby each translation of an inch, the lead screw you rolling once. As the cannula is rotatably fixed to the cannula, the rotation of the lead screw is transmitted to the cannula.
